Ubuntu 22.04: 2023-334b911c45 Major: OpenSSL Vulnerability Detected

cryptography is a package designed to expose cryptographic primitives and

recipes to Python developers.

Security fix for CVE-2023-23931 cryptography is a package designed to expose

cryptographic primitives and recipes to Python developers. In affected versions

`Cipher.update_into` would accept Python objects which implement the buffer

protocol, but provide only immutable buffers. This would allow immutable objects

(such as `bytes`) to be mutated, thus violating fundamental rules of Python and

resulting in corrupted output. This now correctly raises an exception. This

issue has been present since `update_into` was originally introduced in

cryptography 1.8.
